History Series / Stargirl2020

** Cindy's BetaBitch Jenny Williams (sister of Jakeem Thunder) and Green Lanterns' daughter Jennifer-Lynn "Jennie" Hayden.

** The original Doctor-Midnite's daughter Rebecca and the Gambler's daughter Rebecca.

** Henry Sr. and Henry Jr. King.
** Jenny Williams and Jennifer-Lynn "Jennie" Hayden.

** The original Justice Society is introduced with the classic Golden Age lineup. However, in the iconic "table" picture, the Atom and the Spectre (two of the JSA's founding members) are nowhere to be seen. A possible reason for Spectre's absence is that Series/CrisisOnInfiniteEarths portrayed the Spectre as an ultra powerful being that can rival the Anti-Monitor, making the Injustice Society seem like common thugs to the hero if they were to face him.

** Similarly while the children and successors of the Injustice Society are shown like Cameron Mahkent, Artemis Crock, Henry King Jr. etc. Rebecca Sharpe, the granddaughter of The Gambler is also absent in the series as she was a recurring character on Season 4 of ''Series/{{The Flash|2014}}''. Although it's unknown if it also applies to his grandson, Becky's brother, Steven Sharpe V.

** [[spoiler: Sylvester]] accuses the Shade of killing Jay Garrick and Wesley Dodds. However, given the fact that [[spoiler: the Shade only joined the JSA to save Dr Mid-nite]], and also that Jay's helmet was seen covered in ice, it's unclear if the Shade actually did kill them, if he only helped Icicle to kill them, or if the accuser is just flat-out mistaken in what he saw (battles are ''very'' confusing, after all, especially when there are so many combatants involved).

* ImprovFu: Most of Courtney's fights incorporate a bit of this, as while she does know kickboxing and is a very skilled gymnast, most of the people she's fighting massively outclass her; as a result, most of the time you'll see Courtney being tugged out of harm's way by the staff, or tossed around to help her land a kick, or just in general seeing the Staff doing a lot of the work. When Tigress attacks their home, this works to Barbara's advantage too, as the staff quickly moves to protect her too.

** Season 3: The formula is switched up with a HiddenVillain, [[spoiler: ultimately revealed to be a BigBadDuumvirate between a NotQuiteDead [[HijackedByGanon Icicle]] and the Ultra-Humanite]].

** Movies advertised at the Dallas have included ''The Liberty Files'' (a JSA {{Elseworld}}), ''Strange Adventures'' (one of DC's fifties sci-fi comics), ''Comicbook/UnknownSoldier'', ''Comicbook/{{Prez}}'', ''GI Robot'' and ''Comicbook/TheHauntedTank''.

** The ISA's members' powers and abilities change considerably. In the comics, the Gambler dressed like a riverboat gambler and was not a computer hacker, and Green Lantern rather than Dr. Mid-Nite was his nemesis; Icicle was not a businessman; Sportsmaster/Larry Crock never went straight; and so on.

* AbusiveParents: Bad parents/guardians are quite common in this show, whether biological, fosters, or adoptive. Examples include Yolanda’s mother and Rick’s uncle.

Two seasons have been aired so far, and a third one is ongoing. According to Bassinger, Geoff Johns has enough plans for at least ''[[CrazyPrepared five seasons]]'' of the show.

The first season has the group battling the Injustice Society of America, the one responsible for the destruction of the first JSA ten years ago. The ISA includes [[Characters/JusticeSocietyOfAmericaVillains Icicle]] (Creator/NeilJackson) and [[Characters/JusticeSocietyOfAmericaVillains Brainwave]] (Christopher James Baker), both of whom have children who attend Blue Valley High: Cameron Mahkent (Hunter Sansone) and Henry King Jr. (Jake Austin Walker). In the second season, the ISA is reformed by Cindy Burman (Creator/MegDeLacy), the school's most popular student and daughter of the villainous [[Characters/JusticeSocietyOfAmericaVillains Dragon King]], as she teams up with ComicBook/{{Eclipso}} (Nick Tarabay).

* SuperSpecialMove: In the episode "Frenemies Chapter Two: The Suspects", [[ComicBook/StarmanDCComics Starman]] teaches the titular heroine his SuperSpecialMove, the Shooting Star. By fueling with positive feelings the most basic ability of the Cosmic Staff, canceling gravity, the user can turn into a streak of cosmic energy and get launched very high into the sky.

* AccidentalMurder: It is implied that Cindy Burman killed her mother during a tantrum when she was young and still learning to control the modifications done to her body by her father.

* ComicBookAdaptation: The source material (well, FirstAppearance of the character) was in a ''ComicBook/JusticeSocietyOfAmerica'' title by DC Comics in 1999, but [[https://www.amazon.co.uk/Stargirl-Geoff-Johns/dp/1401297129/ref=sr_1_12?dchild=1&keywords=stargirl&qid=1619684691&sr=8-12 the current print version]] is a re-telling of the show, hewing closer to the canon of this show than [[ComicBook/{{Stargirl}} the original comic book]] although it is not a 1:1 adaptation and [[LooseCanon ambiguous if it fits in series canon or not]]. It's also notable as being the first standalone title for Stargirl, since she has always been part of a team in various DC Comics continuities and although a major character, not always TheProtagonist.

* NoSocialSkills
** Larry Crock is very quick to try and befriend Pat, but also basically forces him to join his gym and accept him as a personal trainer, taking on far more responsibility than is needed, pushing Pat very hard from the get-go and even trying to control what Pat eats, and doesn't register that he's annoying. Pat outright comments that the man is ''insane''. The fact he's a retired supervillain might explain his questionable personality.

Two seasons have been aired so far, and a third one has been ordered. According to Bassinger, Geoff Johns has enough plans for at least ''[[CrazyPrepared five seasons]]'' of the show.

->''A new generation of justice.''
-->-- '''Tagline'''

* TheCheerleader: Courtney's classmate Cindy, of the mean variety. She invites Courtney to hang out with her and her friends, then immediately revokes the invitation when Courtney declines to join the cheerleading squad.

* CentralTheme: Legacy. Specifically, the show is about the conflict between a group of adults trying to leave behind a good legacy for those who come after them ([[WellIntentionedExtremist by any means necessary]]) and a group of teenagers trying to live up to the heroic legacy of those who came before them.

The show's cast made their debut in the final part of ''Series/{{Crisis on Infinite Earths|2019}}'', which placed it in the Series/{{Arrowverse}}'s Earth-2. It is otherwise distinct from that franchise, although Creator/JohnWesleyShipp crossed over in the second season of ''Stargirl'', reprising his role of [[Franchise/TheFlash Jay Garrick]].[[note]]His appearance suggests that, as the pre-Crisis Earth-2 was implied to not have a Jay Garrick, the multiversal reboot saw fit to correct that.[[/note]]

** Possibly due to not wanting to overuse them since they have been main villains in the ''Series/{{Arrowverse}}'', Vandal Savage and The Thinker do not appear among the members of the Injustice Society.

** Though they've had a slight settings update, the Justice Society of America and their members are much more truer to the comics than they were in the previous ''Series/{{Arrowverse}}'' shows, even if most of them are [[PosthumousCharacter deceased]].

* AdultFear: Pat repeatedly tells Courtney that she needs to take this seriously because she or others could be killed, but she repeatedly ignores anything he says. In episode seven, Courtney is beaten nearly to death by Shiv, and Pat breaks down upon finding her near-dead because it is ''exactly'' what he was warning her about happening.

* WhoWearsShortShorts: Courtney, who wears athletic shorts as part of her super uniform, as well as denim shorts when she's in California; when she moves to Blue Valley, Nebraska, she changes to jeans.

* VillainWithGoodPublicity: The civilian identities of the Injustice Society's members are respected members of the community in Blue Valley, which is specifically highlighted in the first few episodes:
** Icicle, Jordan Mahkent, is the CEO of The American Dream and well-liked by his employees.
** Wizard's civilian identity, William Zarick, is a councilman who is recognized for helping get Blue Valley High School the funding it needs to be a great school.
** Brainwave's alter ego, Henry King Sr., is a revered neurosurgeon admired for his work at the Blue Valley Medical Center.
** Larry Crock and his wife Paula Brooks, the secret identities of Sportsmaster and Tigress, are respectively the owner of a popular gym in town called "Ripped City" and the gym teacher of Blue Valley High.
** Anaya Bowin, the second Fiddler, is the principal of Blue Valley High.
** Steven Sharpe, the civilian identity of Gambler, is a downplayed example since although he's the CFO of The American Dream, he's a {{Jerkass}} who browbeats his employees.
